Compatibility and Installation
Use a LiFePO4-compatible charger or inverter/charger set for the battery’s nominal voltage and charging profile. Size cables, terminals, disconnects, and overcurrent protection for the expected current. Confirm communication compatibility before relying on closed-loop BMS control. Do not wire batteries in series unless Rich Solar specifically approves that configuration. Installation must follow the manufacturer manual and applicable electrical codes.
Frequently Asked Questions
How much usable energy does it provide?
The nominal rating is 5,120Wh. Usable AC energy depends on inverter efficiency, system settings, temperature, and depth of discharge.
Does it have low-temperature support?
Charging is specified from 32°F to 140°F and discharging from -4°F to 149°F. It should be installed in a suitable protected location.
Can I add more battery capacity later?
The official gallery shows multi-battery configurations. Confirm maximum bank size, cabinet/busbar requirements, firmware, and approved communication protocol for your inverter.
Will it work with my inverter?
It can work with an appropriately sized 48V-class inverter/charger that supports LiFePO4 charging. For communication-based systems, verify the exact protocol and firmware first.
What warranty applies?
Rich Solar lists a 10-year warranty for this model.
